Keratonosis is a medical term used to describe a skin condition or disorder characterized by excessive and abnormal thickening of the outermost layer of the skin, known as the stratum corneum. This condition typically occurs due to an overproduction of keratin, a tough protein that forms the structural component of the skin, hair, and nails.
Keratonosis often presents as rough, dry, and scaly patches on the affected areas of the skin. It is more commonly observed on areas of the body that are subject to constant friction or pressure, such as the elbows, knees, palms, and soles of the feet. In some cases, this condition can cause mild to moderate itching or discomfort.
There are different types of keratonosis, including actinic keratosis and keratosis pilaris. Actinic keratosis is commonly caused by sun exposure and is characterized by the development of rough, scaly patches on sun-exposed areas, such as the face, scalp, and the backs of the hands. Keratosis pilaris, on the other hand, presents as small, red or flesh-colored bumps, often found on the upper arms, thighs, and buttocks.
Treatment for keratonosis may involve the use of moisturizers or topical creams containing exfoliating agents, such as salicylic acid or urea, to help soften and remove the excess buildup of skin cells. In more severe cases, procedures like cryotherapy (freezing) or laser therapy may be necessary.
It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment options for keratonosis.
